Anthropic has already delayed its IPO once, and rumors are now swirling that it may cancel the offering altogether. In September, Reuters reported the listing would slip to late October, and the WSJ later reported a November target so the company could show third-quarter results. The company’s October 26 filing set the company up to begin Nasdaq trading under the ticker ANT as soon as November 16. As that date approaches, however, concerns about the viability of the offering are mounting:

  • The amended S-1 filed November 2 reported Q3 revenue of about $17 billion and roughly $895 billion in purchase and lease commitments. That revenue works out to about $68 billion a year, barely above the $65 billion run rate reported in July.
  • Blackstone reportedly expects Anthropic’s debt to carry a junk rating, which would make raising debt to cover compute commitments challenging.
  • Markets have soured on the AI trade writ large: on November 5th, the Nasdaq 100 fell as much as 6% in an AI-stock liquidation, raising doubts that Anthropic can raise the targeted $100 billion at a $1.5 trillion-plus valuation.

Matt Scherer argued in Tech Policy Press that the SEC should block the offering until Anthropic provides two consecutive quarters of audited financials. Polymarket odds of a 2026 IPO have fallen from 87% to 69%, and on Kalshi odds have fallen from 97% down to 65%.
